<P>PROBLEM TO BE SOLVED: To provide an air conditioning device that has an internal structure which is made difficult to be seen while preventing the sound of air flow from being generated, and to provide a railroad vehicle with the same. <P>SOLUTION: The air conditioning device 18 includes: an inlet port 22; a plurality of cross pieces 70 provided on the inlet port 22, and arranged in substantially parallel with each other while being spaced apart from each other; an intake grill 50 having an inlet surface 74 positioned at an end of the plurality of cross pieces 70 at the suction side thereof; and a fan for sucking air from the inlet port 22 via the intake grill 50. Each of the plurality of cross pieces 70 has an inclined plate 76 inclined with respect to the inlet surface 74 and positioned in order toward a downstream side of a flow of air from the inlet surface 74, and rectifying plates 78 formed continuously from the inclined plate 76 and extending in a substantially perpendicular direction and toward a downstream side with respect to the inlet surface 74. <P>COPYRIGHT: (C)2013,JPO&INPIT |
